New boost and I was wondering what type of oil to use after break in. Regular or synthetic?
I thought that the F150 EcoBoost turbo's are water cooled, not oil cooled. Therefore, you do not have to wait for turbo spooldown-cooldown like other Turbocharged vehicles and be worried about oil temps..??.....the largest problem with the turbo's is that when you shut down the engine, the dino oil sits in the turbo shaft bearing area and just cooks and forms varnishes and cokes that shortens the life of the bearings and seals in the turbos, eventually causing premature failure. Full synthetic oils do not have these properties.
you are correct they are liquid cooled which helps keep temps down while the water pump is running but still require oil lube.I thought that the F150 EcoBoost turbo's are water cooled, not oil cooled.

Dave, in the past I have read that it is best to let the engine "idle a few moments" before turning off the key. I could see this if I was running "hard" and now wanted to shut down the engine. But I would think it it is unnecessary when you were just driving in traffic and shutting down. I know some other engines (with turbos) have aftermarket oil cirulators to minimize coking after shutdown....I'm an aircraft mechanic by trade, and have extensive knowledge of turbo charged internal combustion engines, and the largest problem with the turbo's is that when you shut down the engine, the dino oil sits in the turbo shaft bearing area and just cooks and forms varnishes and cokes that shortens the life of the bearings and seals in the turbos, eventually causing premature failure.

You are correct. The clocking of the turbos allow the thermal siphon effect to pull coolant through the bearing housings as they continue to cool.I thought that the F150 EcoBoost turbo's are water cooled, not oil cooled.

How many miles you been running Amsoil. I am new to the ecoboost. Just deciding if I want to take the plunge.Amsoil in both of my Ecos
